A VS30 Map for California with Geologic and Topographic Constraints

Bulletin of the Seismological Society of America, 2014
Abstract For many earthquake engineering applications, site response is estimated through empirical correlations with the time‐averaged shear‐wave velocity to 30 m depth ( V S 30 ). These applications therefore depend on the availability of either site‐specific V S 30 measurements or V S 30 maps at local, regional, and global scales. Because

Estimates of Vs30 Based on Constrained H/V Ratio Measurements Alone

2009
Most seismic codes adopt the average shear-wave velocity as a key parameter in the first 30 m of subsoil (VS30). Estimates of VS30 are therefore required for both large- and small-scale seismic microzonation. We propose a technique to measure the VS30 based on the horizontal to vertical spectral ratio (H/V) of microtremor recorded at a single station ...

VS30 Map for Mainland China Constrained by Local VS30 Measurements and Incorporating Topographic Slope as Secondary Data via a Cokriging (SCK) Model

VS30 is a widely used parameter for characterizing local site conditions. A VS30 map serves as a fundamental dataset for various studies related to seismic hazard assessment and seismic risk mitigation. In China, over 30 years of extensive engineering projects have generated a wealth of borehole-based VS measurements. We complied a site profile dataset

Determinación el parámetro Vs30 en el Municipio de Teapa, Tabasco

JOURNAL OF BASIC SCIENCES
Anteriormente, el estado de Tabasco era clasificado como una zona de bajo peligro sísmico, debido a la ausencia de registros de terremotos fuertes. Actualmente, existe la evidencia de que sismicidad en estados aledaños, ha causado daños considerables en la entidad.

H/V: un contributo oltre Vs30

2012
Le norme tecniche sulle costruzioni di diverse nazioni prevedono una classificazione semplificata del suolo di fondazione articolata intorno al parametro Vs30 (velocità delle onde di taglio di uno strato omogeneo equivalente a 30 m), sulla base di una presunta correlazione tra questo valore e il fattore di amplificazione sismica stratigrafica ...

DEVELOPMENT OF VS30 MAPS USING MICROTREMORS IN BHUTAN

Bhutan is a landlocked country located in the eastern Himalayas, where the Indian plate is subducting beneath the Eurasian plate, one of the most seismically active regions in the world. The country has the potential for large earthquakes in the future, but accurate evaluations of ground motions have not been conducted.

Effetti di sito e Vs30: una risposta alla normativa antisismica [PDF]

, 2007
L’attuale normativa antisismica italiana ricalca l’Eurocodice 8, il quale a sua volta ha recepito in toto la normativa californiana. Questa duplice traduzione ha purtroppo portato a travisare lo spirito originale, che era quello di fornire una base quantitativa a basso costo, seppure molto approssimata, per la classificazione dei suoli in termini di ...
